Fuel cell device

Abstract

A fuel cell device has a fuel cell unit, a conversion unit for converting material mixtures to a hydrogen-containing fluid stream, a separation device for separating at least one hydrogen-enriched material stream from a fluid residual stream, the separation device being formed as a mass separation device for separating different masses.

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.  
     
         1 . A fuel cell device, comprising a fuel cell unit; a conversion unit for converting material mixtures to a hydrogen-containing fluid stream; a separation device for separating at least one hydrogen-enriched material stream from a fluid residual stream, said separation device being formed as a mass separation device for separating different masses.  
     
     
         2 . A fuel cell device as defined in  claim 1 , wherein said mass separation device has at least one deviating element for deviating the fluid stream.  
     
     
         3 . A fuel cell device as defined in  claim 2 , wherein said deviating element is formed as a circular arc element.  
     
     
         4 . A fuel cell device as defined in  claim 2 , wherein said mass separation device has at least one delay element for delaying a flow speed.  
     
     
         5 . A fuel cell device as defined in  claim 4 , wherein in a region of said delay element a substantially greater flow cross-section is provided then in a region of said deviating element.  
     
     
         6 . A fuel cell device as defined in  claim 4 , wherein said delay element has a first opening for flowing out of the hydrogen-enriched material stream and a second opening for flowing out of the fluid residual stream.  
     
     
         7 . A fuel cell device as defined in  claim 6 , wherein said first opening is arranged in a vertical direction above said second opening.  
     
     
         8 . A fuel cell device as defined in  claim 6 , wherein said second opening is arranged in a vertical direction in a deepest region of said delay element.  
     
     
         9 . A fuel cell device as defined in  claim 6;  and further comprising a dosing element arranged in at least one of said openings.  
     
     
         10 . A fuel cell device as defined in  claim 9 , wherein said dosing element is formed as a cycle valve.  
     
     
         11 . A fuel cell device as defined in  claim 11;  and further comprising at least one element selected from the group consisting of an inflow element and an outflow element associated with said delay element.  
     
     
         12 . A fuel cell device as defined in  claim 11 , wherein said delay element has an inflow opening, said inflow element being arranged on said inflow opening.  
     
     
         13 . A fuel cell device as defined in  claim 11 , wherein said outflow element is arranged on said first opening.  
     
     
         14 . A fuel cell device as defined in  claim 11 , wherein said outflow element is arranged on said second opening.  
     
     
         15 . A fuel cell device as defined in  claim 1 , wherein said at least one element is arranged at least partially in an inner region of said delay element.  
     
     
         16 . A fuel cell device as defined in  claim 11 , wherein said at least one element has a plurality of passages for an inflow and an outflow of the streams correspondingly.
